don't define _POSIX_C_SOURCE in mfd_aes_brute.c if macos

Browse source 
unistd.h in macos has this snippet:

 #if __DARWIN_C_LEVEL >= __DARWIN_C_FULL
 #define _SC_NPROCESSORS_CONF            57
 #define _SC_NPROCESSORS_ONLN            58
 #endif /* __DARWIN_C_LEVEL >= __DARWIN_C_FULL */

__DARWIN_C_FULL is 900000L.

If _POSIX_C_SOURCE gets defined without __DARWIN_C_SOURCE being defined,
__DARWIN_C_LEVEL will be assigned to __DARWIN_C_ANSI, which is 010000L.

Thus this definition will remove _SC_NPROCESSORS_CONF.

If we don't define _POSIX_C_SOURCE, __DARWIN_C_LEVEL will be equal to
__DARWIN_C_FULL, and _SC_NPROCESSORS_CONF will be available.

This commit also includes homebrew and macports prefix definitions for mfd_aes_brute.
